APPENDIX B

ESTABLISHMENT OF TECHNOLOGY REVIEW BOARDS (TRBs)

B.1 SCOPE

* B.1.1 Scope. The information contained herein provides for manufacturer selection of a TRB operation at stated levels. This appendix is not a mandatory part of this standard. The information contained

herein is intended for guidance only. However, once a TRB option is selected and designated as a requirement, this appendix becomes mandatory, and the information contained herein is intended for compliance, other methods of establishing a TRB are allowed with qualifying activity approval. This appendix established requirements for a TRB system which provides for a phased assignment of responsibility to the TRB for the development of design, procurement, manufacturing, test, reliability, and quality assurance standard procedures. A TRB shall be established as noted in table B-I at either level 1 or 2 which defines the extent of control authorized by the qualifying activity. A prerequisite for a TRB shall be an approved MIL-STD-790 system.

TABLE B-I. TRB authority levels. 1/

TRB authority	TRB level
Process/material changes, traceability (B.3.4a)	1 and 2
Alternate methods/equipment, procedures (B.3.4b)	1 and 2
Evaluation corrective action on quality reliability (B.3.4c)	2
Deletion/alternative tests (B.3.4d)	2

1/ Table B-I defines the minimum authority of each TRB level. Actual responsibility and authority will be determined by the qualifying activity.

B.2 APPLICABLE DOCUMENTS. This section is not applicable to this appendix. B.3 REQUIREMENTS

B.3.1 TRB levels or responsibilities. Establishment of a TRB at any level is subject to approval/withdrawal by the qualifying activity at any time. Upon initiation of a TRB, the level of responsibility (see B.3.4) will be assigned by the qualifying activity. The qualifying activity shall provide an overview and determination of the level of authority based upon the experience demonstrated by the TRB. Continual review and monitoring of the TRB operation and procedures will allow the qualifying

activity to determine the assignment of the TRB to the appropriate level, 1 or 2. TRB's are not authorized for class S (space level) programs unless specified in the individual class S product specification. In addition, TRB level 2 is not authorized unless specified in the individual product level specification.

B.3.1.1 Purpose of TRB. The TRB shall assess the impact of proposed changes upon the reliability, form, fit, and function of the product, and oversee review to assure proper implementation of concepts to improve the operational procedures and requirements.
